PIC sounds with 752

I have copied the sounds and sound.cfg into the sound folder of the IFDG 752. When applying TO thrust to the 767 there is a noticable engine "whine" when nearing 90% n1 but I cannot get this to work with the 752. Is there somthing that needs to be changed in the aircraft.cfg for the sound to apply to the 752? I have the PIC panel and panel.cfg in and working properly. Also it sure sounds like the PIC engines(definatly not 2k2 default sound) all except for the "whine."Thanks!!Jon
